Title: Device and method for improving performance of translated program to be executed in server
Inventor: BRYANT CRAIG W
IPC: G06F9/46
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for improving the performance of the execution of a translated language. SOLUTION: The improvement of the performance of the execution of the translated language especially in an application software is realized by moving a translated code to one process (160) first. The process (160) utilizes the translated code and is operated like the library of a translated code routine. Then, when the process (160) is executed, the translated code process (160) duplicates itself and makes a slave (180) execute an already compiled translated code. In such a manner, the translated code of the process is compiled only once at the time of start. It is faster to connect the translated code process, branch it to a slave process and execute a correct code than compiling and executing the correct code when a translated code script becomes large.

Title: Clutch mechanism and ink jet printer
Inventor: NONOYAMA SHIGEO
IPC: F16D41/30
Filed: 1995-04-13
Abstract: PURPOSE: To prevent vibration, noise and wear when a clutch is released from operation, by cutting off and conveying torque from a drive shaft to a driven shaft by a stopper's approach to or retreat from the turning circumferential face of an engagement key. CONSTITUTION: Torque from a drive shaft 6 to a driven shaft 91 is conveyed and cut off by a stopper 19's approach to and retreat from the turning circumferential face of the slope 30 of an engagement key 20. Thus the formation of the slope 30 on the engagement key 20 helps the stopper 19 engages with the slope 30 as if to strand thereon when the stopper 19 engages with the slope 30, exerting a frictional force and prevents reaction. When torque to the driven shaft 92 side is cut off, a ratchet key 24 is prevented from chattering, eliminating noise and vibration, a ratchet teeth 27 and ratchet gear 22 can be protected from wear, and the life of the clutch can be lengthened.
